xdot.py is an interactive viewer for graphs written in Graphviz's dot
language. It uses internally the Graphviz's xdot output format as an
intermediate format, and PyGTK and Cairo for rendering.
xdot.py can be used either as a standalone application from command
line, or as a library embedded in your python application.
